Abstract BACKGROUND: Endovascular coil embolization is an established method of treatment for intracranial aneurysms. The pipeline embolization device (PED) is a low-porosity endovascular stent designed to reconstruct the parent artery and decrease blood flow into the aneurysm. OBJECTIVE: To report a series of 36 patients treated with the PED. METHODS: Thirty-six patients underwent PED placement for aneurysm at the Jefferson Hospital for Neuroscience from October 2010 to November 2011. Clinical charts were reviewed. RESULTS: Thirty-six patients with 42 aneurysms were treated (3 male; 33 female; ages, 34–82; mean age, 60.1 years). Forty-one aneurysms were located in the anterior circulation, whereas one was located at the vertebrobasilar junction. PED placement was successful in all patients and resulted in stasis within all treated aneurysms. Symptomatic postoperative complications were witnessed in 13.9% (n = 5) of patients. These complications included intracerebral hemorrhage (n = 4), dissection (n = 1), symptomatic stroke (n = 2), and death (n = 1). CONCLUSION: Treatment of simple or complex intracranial aneurysms with PEDs alone or in conjunction with coil embolization is technically feasible, and the deployment technique requires a high degree of endovascular skills. Major perioperative adverse events must be studied. Respect for the indications of the procedure is crucial to justify the risk.

Wide Neck

Wide-neck intracranial aneurysms remain a challenge to endovascular treatment. We describe our experience in repairing wide-neck aneurysms of the anterior circulation located at arterial branch points using coil embolization assisted by Y-stenting using two Solitaire® stents. Six wide-neck intracranial aneurysms located on the middle cerebral artery bifurcation 3, pericallosal artery 1, and anterior communicating artery 2 were repaired by Y-stent-assisted coil embolization using two Solitaire® stents. Four cases were incidental findings of aneurysm and two cases were previously treated ruptured aneurysms that had undergone recanalization. All the cases were successfully treated without complications. Follow-up by digital subtraction angiography and magnetic resonance angiography at six months showed the stents to be patent with no recanalization of the aneurysm sacs. Repairing wide-neck aneurysms of the anterior circulation by Y-stent-assisted coil embolization using two Solitaire® stents is a simple and safe method of treating complex aneurysms. While the results are promising, larger series with longer term follow-ups are needed to corroborate that this treatment method is superior to other techniques.

Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017. These procedures were retrospectively reviewed to assess aneurysmal obliteration (Raymond’s classification), the volume embolization ratio (VER) and procedural complications in comparison with 96 conventional coil treatments during the 3-year period up to 2016. Data were matched for aneurysmal morphology (location, maximum diameter and aspect ratio) by the propensity method. Results In all procedures, the TACTICS catheter was atraumatically landed beyond the carotid siphon. There were no hemorrhagic or symptomatic ischemic complications. After propensity matching, 68 procedures were assessed (34 in each group). Achievement of Raymond’s scale 1 (complete occlusion) showed the same frequency in both groups (50% vs. 50%, p = 0.23). The VER was significantly higher with the TACTICS catheter than with the conventional method (34.0% vs. 28.7%, p = 0.003). Conclusion We reviewed our initial experience of the TACTICS catheter. It can be used as an intermediate catheter for safe and effective endovascular coil embolization of anterior circulation aneurysms.

We describe the results of electron microscopic examination in two patients with ruptured intracranial aneurysms who were successfully treated by endovascular coil embolization. The aneurysms were seen completely occluded on the follow-up angiograms. Autopsies of these patients were performed five and 26 months after endovascular treatment when they died of pneumonia and thalamic hemorrhage, respectively. The aneurysms were densely filled with the coils, which were readily identified through the thin and transparent wall of the aneurysmal dome. The orifice of the aneurysm was completely occluded so that macroscopically the coils were not directly visualized through the orifice. To examine any evidence of endothelialization across the orifice of the aneurysms, scanning electron microscopic examination was performed. In both cases, evidence of well regenerative endothelialization was observed across the aneurysmal orifice, being contiguous with the endothelial layer of the adjacent parent vessels. These ultrastructural findings indicate that the aneurysms are completely isolated from the lumen of the parent artery by a continuous lining of the regenerated endothelial cells following the endovascular treatment with coils, and further suggest that aneurysms have a potential of being cured permanently by this treatment modality. This is, to the best of our knowledge, the first report in humans verifying a complete endothelialization of the luminal surface at the aneurysmal neck after coil embolization, as evidenced by scanning electron microscopy.

Lower Morbidity

The endovascular treatment of renal artery aneurysms (RAAs) has lower morbidity and shorter stay lengths compared to surgical repair. Here, we describe coil packing with or without remodeling and assess outcomes and complications. We retrospectively identified the 19 consecutive preventive endovascular RAA coil embolizations done in 18 patients at our center in 2010–2020. Patient and aneurysm characteristics, technical success rate, complications, and recurrences were recorded. Mean patient age was 63 ± 13 years. The RAA was >1.5 cm in 11 cases, and in four cases, the aneurysm-to-parent artery size ratio was >2. Simple coiling was performed for 11 (57.9%) aneurysms, stent-assisted coiling for seven (36.8%) aneurysms, and balloon-assisted coiling for one (5.3%) aneurysm. Technical success rate was 100%. Complete definitive RAA exclusion was achieved with a single procedure for 17 (89.5%) aneurysms, whereas two (10.5%) aneurysms required a repeat procedure. Four minor complications occurred but resolved with no long-term consequences. No major complications occurred during the mean follow-up of 41.1 ± 29.7 months. Coil embolization by sac packing or remodeling proved very safe and effective. Together with the known lower morbidity and shorter stay length compared to open surgery, these data indicate that this endovascular procedure should become the preventive treatment of choice for RAAs.

This investigation aimed to demonstrate the potential of intraprocedural angiographic CT in monitoring complex endovascular coil embolization of direct carotid cavernous fistulas. Angiographic CT was performed as a dual rotational 5 s run with intraarterial contrast medium injection in two patients during endovascular coil embolization of direct carotid cavernous fistulas. Intraprocedural angiographic CT was considered helpful if conventional 2D series were not conclusive concerning coil position or if a precise delineation of the parent artery was impossible due to a complex anatomy or overlying coil material. During postprocessing multiplanar reformatted and dual volume images of angiographic CT were reconstructed. Angiographic CT turned out to be superior in the intraprocedural visualization of accidental coil migration into the parent artery where conventional 2D-DSA series failed to reliably detect coil protrusion. The delineation of coil protrusion by angiographic CT allowed immediate correct coil repositioning to prevent parent artery compromising. Angiographic CT can function as a valuable intraprocedurally feasible tool during complex coil embolizations of direct carotid cavernous fistulas. It allows the precise visualization of the cerebral vasculature and any accidental coil protrusion can be determined accurately in cases where conventional 2D-DSA series are unclear or compromised. Thus angiographic CT might contribute substantially to reduce procedural complications and to increase safety in the management of endovascular treatment of direct carotid cavernous fistulas.

Objective: Validated through experimental studies a new generation of flow diverters (Surpass™ FD) was evaluated for treatment of intracranial aneurysms (IA). We present our multicenter preliminary clinical and angiographic experience. METHODS: To achieve the calculated flow disruption between the parent artery and aneurysm for thrombosis, single FDs were placed endovascularly in parent arteries. Implants measured 2.5-5.3mm in diameter with a length of 10-80mm. Patients were enrolled harboring a wide range large and giant wide-neck, fusiform and multiple small and blister-type aneurysm. Clinical and angiographic follow-up were performed at 1-3, 6, and 12 months. RESULTS: A total of 186 consecutive IA in 161 patients (mean age 57.1 years) were treated at 33 centers. Fifty-three aneurysms were smaller than 5 mm, 64 were 5-9.9mm in diameter, 47 were 10-20mm in diameter, and 22 were larger than 20mm (10.4±0.7mm, neck size 6.0±0.5mm [mean±SEM]) . The aneurysms originated in 63.4% from the internal carotid artery; 22% and 14.5% of the lesions were located in the anterior circulation distal to Circle of Willis and posterior circulation respectively. Technical success was achieved in 182 aneurysms (98%); average number of devices used per aneurysm was 1.05. Permanent morbidity and mortality during the follow-up period of mean 8.4months (range 1-24 months) including periprocedural complications for patients with aneurysms of the anterior circulation were encountered in 5 (3.7%) and 2 (1.5 %) patients respectively and 1 (3.7%) and 4 (14.8%) respectively for patients with aneurysms of the posterior circulation location. One-hundred-ten patients (70.5%) harboring 127 (70.2%) were available for clinical and angiographic follow-up and showed a complete or near complete aneurysm occlusion in 63 (81.8%) of the ICA. Aneurysms of the ICA≥10mm that were completely covered by FD and not previously stent-treated with a minimum of 6 months follow-up available in 16 patients showed a complete obliteration in 81.3% (n=13) and >90% occlusion in remaining 3 patients. CONCLUSION: Preliminary data demonstrate high safety and efficacy of a new generation of FD for a wide range of IA of the anterior and posterior circulation with a single implant.

Meningohypophyseal Trunk

The SolitaireTM AB Neurovascular Remodeling Device (ev3, Irvine, CA, USA) is used to retain coils within an aneurysm, reducing the risk of embolic complications from coil herniation into the parent artery. Stents are deployed after confirming the optimal position of the stent markers across the aneurysm to avoid entry into perforators or branching arteries. Stent marker position is very important to prevent perforating or branching artery infarction. We performed stent-assisted coil embolization using the Solitaire AB stent to treat 2 aneurysms simultaneously. After successful coil embolization, we detached the Solitaire stent in the usual manner. However, the proximal stent marker, which was located at the horizontal segment of the cavernous internal carotid artery, moved into the meningohypophyseal trunk and occluded it. Although the distal markers were positioned optimally, we did not expect the proximal marker to be in the position where it was located. Fortunately, cranial nerve dysfunctions and pituitary deficiency did not develop. It is important to prevent ischemic injury by occlusion of the perforators or branching vessels that can be caused by malpositioned stent markers. We consider where the proximal marker of the stent might be located after detachment.

Abstract Since the International Subarachnoid Aneurysm Trial,1 endovascular treatment has been the favored treatment for appropriate ruptured intracranial aneurysms. While our endovascular technology has advanced to allow us to treat the majority of intracranial aneurysms, simple coil embolization is still the most common modality. This video demonstrates the fundamentals of aneurysm catheterization and coiling for safe treatment. In addition, the set-up and devices are detailed. This video is to add to the library of basic techniques that will aid a large number of practitioners. This patient consented to endovascular treatment. The video demonstrates endovascular coil embolization of a posterior communicating artery aneurysm in a 76-yr-old female who presented with a subarachnoid hemorrhage.
